Design of Self-Healing Supramolecular Rubbers with a Tunable Number of Chemical Cross-Links

Véronique Michaud, Federica Sordo

Supramolecular rubbers incorporating a large number of physical cross-links through cooperative hydrogen bonds display high self-healing properties but limited solvent and creep resistance due to the lack of chemical cross-links. Increasing both chemical c ...

Process-induced strains in RTM processing of polyurethane/carbon composites

Véronique Michaud, Michael Hausmann, Maria Benavente Miana, Luis Pablo Canal Casado

The development of residual strains and stresses is critical to manufacture composite structures with the required dimensional stability and mechanical performance. This work uses Fiber Bragg Grating (FBG) sensors to monitor strain build-up in carbon fiber ...

Evaluation of the interfacial shear strength between pseudoplastic NiTi shape memory alloy wires and epoxy by the pull-out method

Yves Leterrier, Véronique Michaud, Edgars Sparnins

The interfacial shear strength (IFSS) between nickel-titanium (NiTi) shape memory alloy wires, characterized by a nonlinear stress-strain behavior, and epoxy matrix was determined by pull-out tests. Tests were carried out at several temperatures and levels ...

Stress reduction mechanisms during photopolymerization of functionally graded polymer nanocomposite coatings

Yves Leterrier, Véronique Michaud, Florian Dujonc, Michael Hausmann, Tommaso Nardi

From the experimental analysis of the photocuring process in terms of reaction kinetics as well as modulus and shrinkage build-up, the residual stresses arising during the photopolymerization of functionally graded composite coatings based on an acrylate m ...

Assessment of solvent capsule-based healing for woven E-glass fibre-reinforced polymers

Véronique Michaud, Amaël Maximilien Cohades, Inès Richard, Erica Manfredi

Vacuum Assisted Resin Infusion Molding (VARIM) with low vacuum pressure difference was used to manufacture woven glass fibre-reinforced epoxy resin plates, with a fibre volume fraction of approx. 50 vol% and containing ethyl phenylacetate (EPA)-filled caps ...

Effect of interfacial interactions on the electromechanical response of poly(vinylidene fluoride-trifluoroethylene)/BaTiO3 composites and its time dependence after poling

Dragan Damjanovic, Yves Leterrier, Véronique Michaud, Sara Dalle Vacche

Solvent cast and compression molded composite films based on poly(vinylidene fluoride-trifluoroethylene), containing pristine and silylated BaTiO3 particles, were poled, and their electromechanical response (d(33)), their dielectric properties, and the cry ...

Magneto-mechanical actuation of ferromagnetic shape memory alloy/epoxy composites

Véronique Michaud, Susanne Glock, Luis Pablo Canal Casado

Ferromagnetic shape memory alloys (MSMA) exhibit magnetic field- and stress-induced twinning when processed into single crystals, but are brittle and difficult to shape. Embedding slender single crystalline MSMA elements into a polymer matrix can thus prov ...

Electrically conductive self-healing polymer composite coatings

Yves Leterrier, Véronique Michaud, Brennan Margaret Bailey

The goal of the research described herein is the fabrication and assessment of electrically conductive partially-cured epoxy coatings which, upon cracking, autonomously restore barrier, mechanical and electrical properties via a microcapsule based healing ...

Thermal and damping behaviour of magnetic shape memory alloy composites

Véronique Michaud, Susanne Glock

Single crystals of ferromagnetic shape memory alloys (MSMA) exhibit magnetic field and stress induced strains via energy dissipating twinning. Embedding single crystalline MSMA particles into a polymer matrix could thus produce composites with enhanced ene ...

Monitoring strain gradients in adhesive composite joints by embedded fiber Bragg grating sensors

Hans Georg Limberger, John Botsis, Véronique Michaud, Roohollah Sarfaraz Khabbaz, Georgios Violakis, Luis Pablo Canal Casado

The adhesive bonding of composite materials can be applied to assemble light-weight structures for aeronautical applications. However, the application of adhesive bonds in primary load-bearing structures is limited by the lack of adequate techniques to mon ...

A toolbox of oligopeptide-modified polymers for tailored elastomers

Joël Cugnoni, Véronique Michaud, Emmanuel Croisier, Marijana Mionic Ebersold, Holger Frauenrath, Su Liang, Ruben Anton Snellings, Thomas Schweizer

Biomaterials are constructed from limited sets of building blocks but exhibit extraordinary and versatile properties, because hierarchical structure formation lets them employ identical supramolecular motifs for different purposes. Here we exert a similar ...

Blends of oligopeptide terminal polyisobutylene or polystyrene

Véronique Michaud, Emmanuel Croisier, Holger Frauenrath, Su Liang

Various blends of polymers are disclosed, comprising oligopeptide functionalised polymers such as polyisobutylene and polystyrene. Mono-functionalised and di-functionalised polymers (each containing 0 to 5 peptide units beyond its terminal amide group) may ...

Impact properties of shear thickening fluid impregnated foams

Véronique Michaud, Mathieu Soutrenon

Concentrated colloidal suspensions of silica particles in polyethylene glycol exhibit a shear thickening behavior: above a critical shear rate in a confined environment, they show a steep increase of viscosity. This reversible transition from a low to a hi ...

Structural, physical and damping properties of melt-spun Ni-Mn-Ga wire-epoxy composites

Véronique Michaud, Susanne Glock

Ni-Mn-Ga is a ferromagnetic shape memory alloy that exhibits large, magnetic-field- and stress-induced strains via energy dissipating twinning when processed into single crystals. Grain boundaries suppress twinning and render polycrystalline Ni-Mn-Ga britt ...
